CONTAMINATIONS CLASSES

The purity of the coolant lubricant is a decisive factor for trouble-free and low-wear operation of a system. Higher purity ensures less idle time and better results. Consequently, the following contamination classes have been defined to simplify the assessment of the degree of contamination.

Roller separators (MA)

Magnetic separators

APPLICATION AREAS

FAUDI roller separators are used for separating ferritic contaminants and chips in liquids. Typical areas of application are for cold roll-ing, processing steel and cast iron as well as cleaning sinter water. FAUDI roller separators are used as a pre-cleaning stage in filter sys-tems with high demands for filtration quality. This relieves the burden on the downstream ultra-fine filter and increases its service life while reducing the consumption of filter aids. For low filtration quality requirements, FAUDI roller separators can also be used without additional filter technology. They can be installed either in the primary or the secondary flow.

Filtration capacityThe filtration capacity depends on the filter size and the filter medium. Filtration capacities from 50 l/min to 1.500 l/min are possible.

22

FAUDI magnetic rod separators have fewer magnetic rods than comparable products made by competitors. Extensive laboratory tests confirm that FAUDI magnetic rods are more powerful and operate more efficiently and thus the use of fewer magnetic rods in the magnetic rod separator makes more economic sense.

APPLICATION AREAS

Automatic magnetic rod separators are used for separating ferritic contaminants and chips in liquids. Typical areas of application are for cold rolling, processing steel and cast iron as well as cleaning sinter water.

Our automatic magnetic rod separators are used as a pre-cleaning stage in filter systems with high demands for filtration quality. This relieves the burden on the downstream ultra-fine filter and increases its service life while reducing the consumption of filter aids.

For low filtration quality requirements, FAUDI magnetic rod separators can also be used without additional filter technology. They can be installed either in the primary or the secondary flow.

When designing the magnetic rod separators, FAUDI placed special emphasis on an optimal ratio between the diameter and the spacing of the magnetic rods. This ensures the best possible exploitation of the magnetic field. As a result, an essentially “closed” magnetic field, or a “chain curtain” is created.

Rod separators (MSA 2000 – MSA 7500)
